Most people don’t realize how easy blimps are to use. Our 3x8ft, 5x12ft, 8x18ft come with tail fins and their guy lines attached and ready to inflate, right out of the box! Just fill them with helium, attach them to an anchor point and let them go up the full length of their tether lines (135′). There is no mystery about flying an advertising Tube. Instructions come with each size Tube, explaining how much helium is needed, where to get it, what to do about everything.
